POWER WINDOW CONTROL SYSTEM Driver Side Power Window Auto Up / Down Function does not Operate with Power Window Master Switch
| DTC Code | DTC Name |
|---|---|
| Driver Side Power Window Auto Up / Down Function does not Operate with Power Window Master Switch |
DESCRIPTION
If the manual up and down function operates normally but the auto up and down function does not, then fail-safe mode may be functioning.
If power window initialization has not been performed, the auto up and down function will not operate.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
Inspect the fuses for circuits related to this system before performing the following procedure.
The power window control system uses the LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
If the front power window regulator motor assembly LH (for LHD) or front power window regulator motor assembly RH (for RHD) has been replaced with a new one, initialize the power window control system.
When the ECU determines that the front power window regulator motor assembly LH (for LHD) or front power window regulator motor assembly RH (for RHD) has a malfunction, DTC B2311 is stored.
After the catch protection function operates, the auto operation is not performed the first time auto up is performed. All auto up operations performed after the first operate normally.
If the pulse sensor built into the front power window regulator motor assembly LH (for LHD) or front power window regulator motor assembly RH (for RHD) is malfunctioning, the power window control system enters fail-safe mode. The remote up and down function cannot be operated during fail-safe mode. However, the power window can be closed by holding the power window regulator master switch assembly at the auto up position, and opened manually by pushing down the power window regulator master switch assembly.
